Thanks,

Namespaces
Namespaces allow to group entities like classes, objects and functions under a name. This way the global scope can be divided in "sub-scopes", each one with its own name.

The format of namespaces is:
namespace identifier
{
entities
}

The example is:

// namespaces
#include <iostream>
using namespace std;

namespace first
{
int var = 5;
}

namespace second
{
double var = 3.1416;
}

int main () {
cout << first::var << endl;
cout << second::var << endl;
return 0;
}
